Understand your startup's financial health with a step-by-step guide to creating a cash flow statement. Learn to track survival, manage burn rate, and make smarter financial decisions.

A profitable startup can still be weeks away from insolvency. This isn't a paradox; it's a cash flow problem that many founders learn the hard way. Unlike the income statement, which shows profitability on an accrual basis, the statement of cash flows gives you a brutally honest look at the cash moving in and out of your business. This tutorial provides a step-by-step guide to creating an accurate cash flow statement, so you can understand your startup’s financial health and make smarter decisions.
For a startup, cash isn't just king—it's the entire kingdom. The statement of cash flows is less about proving profitability and more about tracking survival. It reveals your burn rate, measures runway, and shows how effectively you’re converting investment capital into operational motion. For instance, you could land a massive contract and record a huge jump in net income, but if the client has 90-day payment terms, you won't see that cash for three months. That gap between recorded revenue and actual cash in the bank can sink an otherwise healthy business.
Investors pay close attention to this document. A predictable cash burn signals disciplined operations, while erratic cash flow may suggest a lack of foresight or poor management of working capital. For founders and their finance teams, it's a vital tool for planning when to hire, whether you can afford that new equipment, and, most importantly, when you might need to raise your next round of funding.
Before you begin constructing the statement, you need three key financial documents. Having these accurate and ready will make the process significantly smoother. Modern cloud accounting platforms like QuickBooks Online, Xero, or Wave are designed to generate these reports directly, saving considerable manual effort.
A statement of cash flows is always organized into the same three sections. Understanding what each section represents is fundamental to both its creation and its interpretation.
1. Cash from Operating Activities (CFO): This is the cash generated by your startup's core business activities. It includes the cash received from customers and the cash paid to suppliers, employees, for rent, and other operational expenses. A positive and growing CFO indicates a healthy business model that can sustain itself without constantly relying on outside funding. For startups, this number is often negative in the early days, but tracking its trend toward positive is a key performance indicator.
2. Cash from Investing Activities (CFI): This section covers cash used for or generated from the purchase and sale of long-term assets. For a startup, this typically means cash outflows to buy computers, equipment, furniture, or intellectual property. If you sell off any of these assets, the cash received would show up here as an inflow. Significant investments in assets often signal a period of growth and expansion.
3. Cash from Financing Activities (CFF): This shows how your startup is funded. It includes cash received from investors when you issue stock, funds from bank loans, and contributions from owners. On the outflow side, it includes principal repayments on debt and payments of dividends. For VC-backed startups, this section will light up with large cash inflows after a funding round closes.

There are two accepted ways to prepare the cash flow statement: the indirect method and the direct method. While both arrive at the same final number for total cash flow, they present the Operating Activities section very differently.
Let's walk through building your statement, starting with a hypothetical net income of $20,000 for the quarter.
This is the easy part. Pull the net income figure directly from the bottom of your income statement for the period. Let's use $20,000.
Your income statement includes several expenses that don't actually reduce your cash balance. You need to add these back to your net income. The two most common for a startup are:
Let’s assume you had $1,000 in depreciation. Your subtotal is now $20,000 + $1,000 = $21,000.
This is where the comparative balance sheets become necessary. Working capital refers to your current operating assets and liabilities. The key is to remember how a change in each affects your cash.
Imagine your Accounts Receivable grew by $5,000 and your Accounts Payable grew by $2,000. Your adjustment would be -$5,000 and +$2,000. Your ongoing calculation for operating cash flow is $21,000 - $5,000 + $2,000 = $18,000 (Cash from Operations).
Now, look at the long-term asset section of your balance sheet. Did you buy any property, plant, or equipment (PP&E)? Let's say your PP&E account increased by $10,000 because you bought new office furniture. That's a $10,000 use of cash. So, your Cash from Investing = -$10,000.
Finally, examine changes in long-term debt and equity. Did you take out a loan, or did an investor put in money? Let's say you closed a seed round and issued $100,000 in stock while also repaying $5,000 of a business loan. Your net financing cash flow would be +$100,000 - $5,000 = $95,000 (Cash from Financing).
Now you sum the three sections to find the total change in cash for the period:
Net Change in Cash = CFO ($18,000) + CFI (-$10,000) + CFF ($95,000) = $103,000
To confirm your work, this result should match the change in your cash balance on the balance sheet. If your Cash at the start of the period was $50,000, your ending cash should be $50,000 + $103,000 = $153,000. If this number matches the cash balance on your period-end balance sheet, you’ve done it correctly.
When preparing this statement, early-stage companies often run into a few common issues that can distort their financial picture:
Upload tax documents, filings, and IRS letters—turn them into clear, actionable insights with verified citations. Save hours on research.
Creating your first statement of cash flows demystifies where your money is truly going. It transforms foggy financial questions into concrete numbers, providing the clarity needed to manage runways, secure investor confidence, and steer your business toward a stable financial future. For any founder or adviser, it's an indispensable report.
Looking forward often involves navigating tax issues around fundraising, R&D credits, or SALT compliance, where accurate answers are critical. For these complex planning questions, spending hours looking for reliable information isn't an option. Our platform, Feather AI, gives you immediate, citation-backed answers from authoritative tax sources, allowing you to move quickly from a question to an informed, strategic decision.
